Marketing is one of the most important factors in determining the success of any fruit and vegetable farming enterprise. Marketing includes all the operations and decisions made by producers. These decisions range from deter-mining the most marketable crops for production to deciding how to best deliver quality produce to the consumers at a profit. However, contrary to popular belief, marketing does not begin after a crop is produced. Instead, marketing alternatives need to be considered even before production takes place.

Recent environmental and food safety concerns in the United States produce sector have brought about increasing interest in organic fruit and vegetable production as an alternative to traditional fruit and vegetable enterprises. As a result, the production and marketing of organic crops has expanded steadily during the 1980s. However, as more organic producers enter the industry and it becomes more and more competitive, existing producers are forced to become better growers and more effective marketers.
<h3><u>Answer and explanation;</u></h3>
- Density plays an important role in the study of Earth. It affects Earth's climate, plate tectonics, and subduction.
- <em><u>Subduction occurs at the convergent plate boundaries. Density plays a major role for subduction to take place. Subduction is driven by the excess density of the lithosphere compared to the underlying asthenosphere.</u></em>
- <em><u>Oceanic plates are denser and colder than continental plates, because the ocean cools them. Subduction can occur between an oceanic plate and a continental plate, or two oceanic plate or two continenetal plates.</u></em>
- During subduction between oceanic and continental plates, mantle convection drags the denser oceanic plate downwards and forces it down into the asthenosphere.
- During subduction between two oceanic plates, mantle convection drags the older, denser oceanic plate downwards and forces it into the asthenosphere.
- During subduction between two continental plates, there is no mantle convection, because the two plates are of similar densities.
